ResumoA new family of thiol-derivatized metallophthalocyanine has been synthesized. The electrochemical behaviors of the complexes have been investigated. The modified glassy carbon electrode using the electropolymerized manganese complex (poly-MnTMPyrPc) was characterized in aqueous solution. The result indicates that the complexes are easier to electropolymerize in dichloromethane (DCM) than in dimethylformamide (DMF). The poly-MnTPyrPc-modified electrode showed pH dependence within the pH range studied (2–8). The cathodic wave of the electrode showed more pH dependence than the anodic wave. Poly-MnTPyrPc could catalyse the reduction of oxygen.
